To all whom it may concern.

Be it known that I, ALFRED GODFREY, a subject of the King of Great Britain and Ireland, residing in Middlesex, England, have invented new and useful Improvements in Cigarette-Packet Forming and Filling Machines, of which the following is a specification.

This invention relates to improvements in cigarette packet forming and filling machines in which cases of paper, cardboard or other similar material are used and has for its object to provide improved means for cutting the paper or cardboard for these cases to the desired shape, the waste cuttings from the blank being held and discharged clear of the die, whereas the blank is creased at the folding edges.

The invention further consists in the improvements and constructive details of the above cutting and scoring means set forth more fully hereinafter.

The invention is illustrated by way of example in the accompanying drawings in which like reference letters refer to like parts in the various figures.

Figure 1 1s a slde elevation of a machine constructed in accordance with my invention.

Fig. 1 is an elevational view of the spring bumper in detail.

Fig. 1 is a plan view of Fig. l. with some portions removed to show parts beneath.

Fig. 2 is a part plan showing a section through the cutting die.

Figs. 2, 2", 2, show different views of the die casing for collecting the cuttings and discharging them clear of the die.

Fig. 2 is a part plan of the paper feeding device showing an automatic side lay for registering the position of the paper blank when being fed under the cutting die.

Fig. 2 is a front view of the die showing the stop bar. a

Fig. 2 is a plan of the same showing the retaining knife edges in the die casing and means for reventing the dust getting under the die.

Fig. 3 is a detail view of the paper feeding cutting and creasing mechanism.

Fig. i) is a view of a blank of cardboard or paper as fed into the machine and Fig. 3 is a view of the same blank as cut and creased before folding.

Fig. 4 is a detail view of the cut blank feeding mechanism.

Fig. P-is a plan of the grippers and operating gear of the cut blank feeding mechanism.

Fig. 4} shows two views of the taper fingers carried by the die casing for registering the position of the blank before being grlpped one view being a front elevation and the other view a side elevation in section.

Fig. 4 is an end view of the stop bar shown in Figs. 2 and 3.

Fig. 5 is a detail view of the supporting means for the main shaft to prevent distortion of same during the cutting and creasing operations. v

Fig. 6 is a view showing a micrometer adjustment for the connecting rod ends of the pressure mechanism so as to insure a minute regulation of the pressure upon the cutting and creasing dies.

In carrying my invention into effect I arrange a feed table a on which the sheets of paper or cardboard can be fed by hand and in connection with such table I arrange advancing and retiring fingers b which have a reciprocating motion given to them by a cam 7) operating the bell crank 5 connected by means of a forked end I) with a pin 72 carried by a slide 5 to which the fingers b are-rigidly attached; the motion of the bell crank 2 in the opposite direction to that given it by the cam b is effected by a spring 6 The definite register is effected by means of an automatic side lay 79' shown in Fig. 2 operated by a lever 12 pivoted on the frame at b and under the control of a spring 5 which draws the lay 5 into its operative position. The lever 12 is adapted to co-act with an inclined lane I). shown in Fig. 2" so that the lay b is put into open position when the paper blank is fed forward between the fixed lay o and the automatic lay b The rising of the part 0 brings the inclined plane 6 out of contact with the arm a sliding I part Is b and thus allows the lay blank against the lay Z2 The endsof the fingers Z) are adapted to engage with'the edge of the paper or cardboard lying on the table a and feed it forward to a-position of definite register and b to press the to retire again to engage the next piece of paper asthe machine. moves.

The definite end position of the paper or cardboard. is effected by a. rotary bar Z7 mounted on bearings b on the feed table a' and provided with stop "projections b against which the edge of the paper can abut, the abutting surfaces being of .circular formation struckfrom the axis ofthebearings I). This. stop bar 6 also carries gripping fingers whichv are adapted to grip the paper upon-the upper surface of the spring table a when thelatter is returning after the cutting; and creasing operations so as to hold the cut and creasedv blank gfirmly in register until gripped by grippers (Z hereinafter described. The barb 'is operated by a lever 6 spring pressed by a spiral spring-J)? in one direction and in the other by a bellcrank lever 72 pivoted'onthe frame a andfhavingwabeveled end b 9-to engage the cutting die-c Whenthe reverse motion of the part 74 viz: from right to left takes place theroller b mounts the-higher portion of 6 the stops E and grippers b are turned rightup into the position to allow the paper to pass underneath them, and then to drop. back to the position when the stopsb 'are ready to receive the next paper sheet. These parts are shown in detail inFigs. 2 and 2, and as the blank is 7 fed up by the fingers-b against the stops 6 and as the surface 6 moves to the-left it will be seen that the beveled: end Z2 retires from under the arm 61 andallows the fin gers b to descend under the pressure of the spring 6 and thuscausethe paper to be gripped bythet-able c When the .paper is thus-in its registered position in one direction as a blank,.as shown in Fig. 8, and as described, it. lies within the cutting and creasing die, a the lower. portion clof. which is. rigidly fixed. on the bed of the machine. while the upperv portion c is reciprocated' by a tension rod 0 connecting rod 0* and pivotedlever, 0. oneenclof which engages with a grooved cam 0 'llhelower-portion 0. of the dieis: provided 'After the paper; is thus in (Figs. 1 and 5) fixedly on each side and having surfaces inclined totlle direction of movement of the part' c soas to engage the edges "of the blank and register. it laterally in position, while it is free and before the fingers 25 its registered position laterally on the table 0 and is held press upon it. 7

A limiting; stopdevice c" is arranged at each sideof' the die 0 in order-to form a definiteabutmentagainst which the table 0? can" be forced? byjits springs 0 This 1 device 0 oversails the sliding j oint between the table 0 I and the die 0 and thus prevents: dust or foreign 'matter getting between the under side of thetable and-the die 0 so asto insure the table being in contact with theistops 6 at the end'of its upward movement. The cutting and creasing operation havlng thus 3 p been completed'the blank has thej shape indicated in Fig. 3 the dottedlinesfindicating the lines of creasing along which 'the subsequent foldingis totake place,

In order to preventthe shaft m carrying the cam 0", from distortion or bending under the load, transmitted through. the rod 0 when the cutting and creasing operation is efi'ected, it is formed'withacircular periph ery and is: inclosed in a bearing orstay 0 of the machine.

After the cutting and creasing operations the cut paper is, seized on the lever (Z and engaging with a cam d.

The grippers d are pressed into their'operative position by means of a spring pressed plunger (Z engaging on the underside of the rear arm of the grippers.

In order to' open the grippers the rear arm has a lateral extension 03 which contacts during the reciprocating movement with a spring pressed pivoted switching arm (5 so that on the forward movement the engages on the under inclined face of the arm (Z10 until nearing the end of the reciprocating stroke the extension d trips past the lower end of the inclined sur face so as to allow the spring pressed plunger d to force the grippers into contact with the paper. On the return stroke, the extension (Z rides over the upper inclined surface of the arm d which being spring pressed is forced in a downward direction against such spring and thus allows'the extension (Z-to pass freely over itand when the said extension has passed the arm 6 the latter rises again under the action of its spring into position ready for the next forward stroke. 'The arm d is prevented from an upward movement above the position shown in Fig. 4: by a fixed stop (Z against which it abuts.

As the grippers 0Z reach the forward end that the cut blank is disposed over the folding die c'the lateral extension (5 is disposed under a pivoted arm (i operated by a connecting rod (1, pivoted lever (1 and cam (Z so as to raise the end (I of the grippers (P from the paper and release it. In order to take up the momentum of the slide (i at the end of the back- \vard stroke a spring buffer d is arranged in the frame and shown on an enlarged scale in Fig. 1.

It is found to be desirable to provide simple means for finely adjusting the various parts of the mechanism so as to get the desired pressure and registration of position. In Fig. 6 is shown a method of micrometer adjustment to the connecting rod 0 comprising a sliding block 0 engaging in a parallel recess, at the upper side is a jamming screw 0 bearing against the block 0 on the lower side an adjusting screw 0 on the head of which is an index 0 which can be moved in conjunction with graduations 0 on a circular part 0 of the rod 0 The adjustment is effected by loosening the screw 0 and then turning the adjusting screw 0 through the proper number of graduations and finally looking it by tightening the jamming screw 0 lVhat I claim is 1.
